Little bit of a bug with System Center Configuration Manager current branch (1511) when you are using Microsoft Intune in a hybrid configuration and also are using native Mac management (HTTPS/PKI).

If you are managing Mac’s through MDM (supported with 1511 and Intune hybrid) then this would not apply to you.

If you have a Terms & Conditions policy created, then your Mac devices will not finish enrolling properly. Unfortunately, the T&C doesn’t even need to be deployed, the policy just needs to exist. You will be able to install the Mac client and complete the enrollment process, however the Mac devices will never show up in the ConfigMgr console. It appears to an issue in processing the mobile policies (as Mac devices are treated as mobile devices).

By deleting the Terms and Conditions, your Mac devices will finish enrolling and will show up in the console shortly there-after.
